MN CALAO against its type
Built in 2013, it is 11 years newer than the median ro-ro ship on this register, which was built in 2002 (281 vessels with a known build year). At 23,673 gross tonnage it is larger than 58% of the other 269 ro-ro ships with a recorded tonnage. It is one of 11 ro-ro ships here under the France flag, 3.5% of the 311 on the register. The same builder is recorded for 983 other vessels here, 18 of them ro-ro ships. National Shipping Company is linked to 3 vessels on this register. The returns for 2018–2022 all give MARSEILLE as port of registry.
Its 15,740 t of CO₂ for 2022 is 35% below the median of 24,369 t among the 238 ro-ro ships on this register that reported for 2022. Per nautical mile it emitted 357.9 kg CO₂, close to the type median of 342.5 kg. It logged 3,270 hours at sea against a median of 5,169 hours for its type that year. 6.2% of its 2022 emissions were at berth; the median for ro-ro ships was 4.6%. Across 5 years with reported emissions, the highest was 2020 (17,933 t) and the lowest 2018 (12,954 t). Its efficiency percentile within the type went from 87 in 2019 to 95 in 2022 (lower is more efficient). The one sister ship listed below with a 2022 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2022
Position 179 of 188 qualifying ro-ro ships by EEOI, at the 95th percentile. The dashed line is the type median, 86.8; this vessel reported 219.1.
EEOI divides emissions by transport work, which for this vessel and year was 71,846,996 tonne-miles over 43,978 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2022 was 21.5% higher than in 2018, for EU/EEA voyages only.
From 2021 to 2022, emissions fell 8.2% while distance sailed fell 9.9%and CO₂ per nautical mile rose 2.0%.That points mainly to how much the vessel sailed, rather than the other.
